What is your opinion about Heroes IV?

Why be so harsh? It's just not a very successful experiment! The graphics are great, and the gameplay isn't completely terrible.

I said I wouldn't generalize. Besides, I didn't criticize the graphics, but the gameplay still isn't great. Especially when compared to the other installments. Overall, it's an unsuccessful experiment by 3DO, and also the last one.
In my opinion, they decided to repeat themselves and create something similar to the third part. And the biggest drawback is that they combined two castles into one, and when building creatures, you have to choose one of the two. And there are no upgrades either. Overall, it's a matter of personal taste.
